| Abstract | Forward symbolic execution is a program analysis technique that allows using symbolic inputs to explore program executions. The traditional applications of this technique have focused on programs that manipulate primitive data types, such as integer or boolean. Recent extensions have shown how to handle reference types at their representation level. The extensions have favorably been backed by advances in constraint solving technology, and together they have made symbolic execution applicable, at least in theory, to a large class of programs. In practice, however, the increased potential for applications has created significant issues with scalability of symbolic execution to programs of non-trivial size---the ensuing path conditions rapidly become unfeasibly complex.We present Dianju, a new technique that aims to address the scalability of symbolic execution. The fundamental idea in Dianju is to perform symbolic execution of commonly used library classes (such as strings, sets and maps) at the abstract level rather than the representation level. Dianju defines semantics of operations on symbolic objects of these classes, which allows Dianju to abstract away from the complexity that is normally inherent in library implementations, thus promising scalable analyses based on symbolic execution. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
